Reps of the Reincarnated Shinobi
When a Naruto superfan meets an absurd end—crushed by a truck that mysteriously flies into his fifth-floor apartment—he wakes up in the world he only knew from anime. Now a kid in the Hidden Leaf Village, he's enrolled in the Ninja Academy alongside none other than Naruto Uzumaki himself.
But he's not just another background character. Gifted with the Ultra Gainz Exercise System, he can unlock mind-blowing chakra control, taijutsu, and even forbidden techniques—if he’s willing to train like a beast. Push-ups give him strength, sit-ups boost chakra, and burpees unlock jutsu. The catch? Skipping workouts means losing progress, and the system will punish laziness.
Armed with gym knowledge from the modern world, a no-excuses grindset, and a cheat system that rewards effort, he's ready to flip the script of the ninja world—one rep at a time.
This is the story of a reincarnated underdog who turns fitness into ninjutsu—and sweat into power.
